Track 5: Concrete Pavement Equipment Automation and Advancements
Stringless Paving (5.2.1)
GPS accuracy is good vertically to only one inch, so to get the proper accuracy in the z position you can use laser augmentation on the 4 wheeler. An alternate to the 4 wheeler is to shoot the existing pavement with total station.
Reference points are 250’+ apart and stagger on opposite sides. Vertical (Z) coordinate for reference points established by 3 wire level.
Measuring “Attitude”
The prisms on the machine tells the total station where the machine is at for x,y,z. This information is related to the computer model on the machine from the total stations through radios on the machine. The model then knows where the machine is at and tells the machine what elevation in needs to be on each of the four corners of the pan.
Track 5: Stringless

Track 1: Performance-Based Concrete Pavement Mix Design
Evaluation of Test Methods for Permeability (Transport) and Development of Performance
Guidelines for Durability (1.2.5)
Project ObjectivesDevelop a test procedure that directly evaluates the transport properties of concrete and relates these to anticipated performance with the use of exposure conditions. • Evaluation of existing transport test procedures• Development of new, or improvement test
procedures • Correlation between transport properties and
existing ‘durability’ tests.• Develop guidelines to relate permeability,
exposure conditions, and field performance for use in specifications and quality control
Track 1: Permeability
Mechanism of Electrical Conduction in Concrete
Concrete is a composite:
• Solid phase (unhyd Cement, CSH, CH,…); σsol ≈ 10-9 S/m
• Liquid phase (pore solution);σliq ≈ 1 S/m to 20 S/m
• Vapor phase (air voids, emptied pores); σvap ≈ 10-15 S/m
(Rajabipour 2006 based on results of Hammond and Robson 1955)
(Christensen 1993)
(Aplin 2005)
Solid Vapor
Liquid
Flow of electricity is essentially ionic and through material’s liquid phase

research and technology transfer and serves as a framework for stakeholders committed to the value of innovation and implementation of new knowledge and approaches. It is not just a listing of 250 research project statements that outline research needs.
1. Looking forward from a state’s perspective, how can the CP Road Map further facilitate information exchange, efficiency, and effectiveness in addressing needed concrete pavement research and technology transfer?
2. Where should the CP Road Map’s pooled fund activities be focused to bring the greatest value to the states?
4. What are your ideas on how the OSG can be most effective within the funding provided: i.e., what activities, efforts, products, etc., do you think will bring the most value?
5. How can this pooled fund work with other existing efforts, i.e., other concrete pavement pooled funds and other related research?
